The Welch Allyn DS66 trigger aneroid is an innovative gauge with a trigger-style air release valve. The ergonomic design features soft plastic inserts at key touch points that make it comfortable to use. Featuring gear-free technology, this gauge will remain in calibration longer than traditional aneroids, continuing to provide accurate readings over time. This set comes with a reusable, two-piece adult cuff with a single tube.
